If your gonna go the methanol route however, then why not consider going for one of the longer chain alcohols like Butanol which can be put into your car's gas tank with NO MODIFICATIONS to the internal combustion engine...

Also, keep in mind that the energy content of Methanol is very low (less than half the energy content of Gasoline)...

Gasoline has 125,000 BTU's/US Gallon
Butanol has 104,800 BTU's
Ethanol has 84,400 BTU's
Methanol has 62,800 BTU's

Of course the most compact energy source would be Diesel Fuel:
Deisel Fuel has 147,000 BTU's/US Gallon
Bio Deisel is slightly less at approx 146,000/BTU's/US Gallon
But the environmental whackos hate deisel because its noisy and they have images of smokey exhaust fumes dancing in their little heads.
